A ring, A', surrounding an eccentric disk, B', is `attached no the lower ond of the rod V, so that the end,c,ot' the beam S-'ean be raised or lowered hy'roteting the shaft C' of the eccentric B' by means of the crank D or like device. A cani, E', is also inountedon the ,shaft C', and is surrounded by a. frame, F', connected with eroihG, whchis also'con. ',.nectedv with a. spring-pewl, H' ,engaging with-a.

The plate MI' is prol vided with 'n. njannnlar strip; N',- of rubber, leather-,or .analogous material, uponl which strip- 'the articles 0' that are tobe' ground rest, .so as to have u soft and yielding bearing.

The' articles are placed.- into the E rings P',a.nd are heldyeldingly by the springs {Q-f.' The weber, that must be poured upon the erticles during the grinding, is conducted to each erticl'e' by a ilexible tube, and ilows off the annuler gutter S' of the plete L';

The Adistance from the end d of ,the beam S to the bottom point of the grinding-stone A lmns't bia-regulated according to the sizes-of the stone A or the articles 0'; :pose the oog-wheell1 is nrrengedto engage lwith `a barrel-pinion, T', wheel, m., at its lower end, und is journaledV M', is mounted' through the e'perturesz ofthe pme 1nl into.

and a cogwhee1,p, at the other end of this shaft o engages with the cog-wheel r of a vertical shaft, s, provided with a hand-wheel, V', at the lower end.

There are to be as man y teeth in thc ratchetwheel J' oi' thc shaft K' as there are holdingrings P' on the plate M'.

'As the tube D rests upon the top of' the bell J which is rigidly attached tothe tube or rod 1f, it is evident that the tube D will rise and descend with the tube K.

, The operation is as follows: The articles to be ground are placed upon the disk or plate M', and are held in their properV position 4by the rings I". The rods 0 and Q are then adjusted according to the size ot' the article O' or the stone A by turning the hand-wheel V', for thereby the barrel-pinion T'is rotated, and as the cogwheel H engages with this barrelpinion '1" in all its positions, this 'wheel H andthe sleeve P attached thereto will also be rotated; but as the two ends of,l sleeve P are threaded inversely the rods O und Q will be separated if the wheel V's rotated in one direction, and will be drawn together if rotated in tho opposite direction. The weight U is then n djustcd on the beam S, according to the weight suspended from the end d of the same,

so esto balance it. By rotating the crank D'v a very short distance from left to right the end o of the beam S will rise and the end d descend, and the stone A will come in contact with the article O' to be ground; but at the same time that the above movements take place the cam E' pushes the frame F' and the rod G' in the direction ofthe arrow a', and the spring-pawl H' rotates the shaft K' the distan ce of one tooth of 'the wheel J', and the plateM' is-rotated the distance occupied by an article, O', so that by the oscillating movement of the crank the stone A is raised and the pawl H' is drawn back, and then the pawl is pushed forward, the disk M' rotated, and the stoneA lowered. The tube D' is rotated by means of' the belt W passing around the pulley G. As the bell J is rigid and; the4 pinion N that engages with the teeth of the bell is rotated on the vertical axis by the fork (J,it follows that the pinion must also rotate on-its horizontal axis-that is, it 4rotates'on its shaft B, and al: the same time runs around iu n circle'parallel .to this axis but as the stoneA. is mounted ou the shaft B, it will rotate with this shaft, but at the sumo time it will rotate on a. dinmetricnl vertical axis, as itis mounted in the middle of the shaft B, mounted in the fork O, which is rotated in the verticnl'oxis.

The stone A may be replaced by others of different size or structure, according to the hardness, nature, or sizeof the glass article that is to be ground.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1.. A machine for grinding glassware, made substantially as herein shown and described, and consisting of a grinding-stone mounted on by means of which the stone may be raised from or lowered upon the article to be ground, as may be required.

2. In a machine for grinding glassware, the combination, with the suspended rotating grinding-stone A, of an adjust-able suspension device, of the pivoted beam S, the connectin g-rod V, the eccentric B', and the shaft C', substantially as herein shown and described, and for the purpose of raising the stone A by means of a slight rotation of the shaft O', as

'set forth.

3. In a machine for grinding glass, the conibination, with the suspending-rods Q and O. having inverse screw-threads at the ends, of the sleeve P, threaded inversely at the ends, the cog-wheel H, the barrel-pinion T', and a train of gearing and shat'tin g for rotating the barrel-pinion T' at will, substantially as herein shown and described, and for the purpose -of adjusting the length oi' the suspending device ofthe grinding-stone according to the size of this stone or the size of the article to be ground.

Il. In a machine for grinding glassware, the

combination, with the plate M', of a series ot' radially-pivoted holdingrings P', provided with cushioned springs Q', substantially as herein shown and described, and for the purpose of holding the articles securely.

5. In a machine for grinding glassware, the combinatiomwith the plate M',having pivoted 1 holders P' for the articles to be ground, of the shaft K', the ratchet-wheel J', having as many teeth as there are holders P' on the plate M', and ofthe sprii1gpawl H', substantially as herein shown and described and for thcpnrpose of 'rotating the plate alike distance every time.

6. In a machine for grinding glassware, the

B', and the frame F', ot' the rod G', the pawl Il', the ratchet-wheel J', the shaft K'the plate M', the connecting-rod V, the pivotcd beam S, and the grinding'apparatus suspended from 'the same, as set forth, for the purpose of passing the articles to be ground under the stone Vand lowering the stone upon the article by a slight rotation of thc shaft 0'.

7.' In a machine for grinding glasswnrc, n

.rotating grinding-stone, an adjustable snspension-rod, a pivotcd beam to which the suspension-rod is attached, cred for raising or lowering the ends of the beam, au eccentric for operating this rod, a revolving table for holding the articles to be ground, and e pawl connected with the shaft of the eccentric for rotating the table, all these parts in combina- Wituesses: EMMANUEL BUTTER.
